Ok. I am trying to make a 2nd floor loft. North and South walls need to be 3 feet tall on the 2nd floor. Center roof ridge needs to be 8 feet tall. Total space is a 26X24 foot. The first floor is devided into 2 rooms. Each 26X12. The North room is the ground floor of the studio appartment. South room is going to be an extention of my wood shop. The north room is open on all floors with a valtided ceiling. Over the south room is the loft. How am I able to make the north and south walls both to be only 3 feet high, and have the east and west walls go from the 3 foot hight to a 8 foot center? Attached is a very rough pic of what I am talking about. (It is Virtual Architech Ultimate that I am using)
